EXECUTIVE FUNCTION

Executive Functions

Abilities guiding behavior towards achieving goals.

Frontal Lobe

Brain region crucial for executive functions.

Novel Situations

Circumstances requiring new behavioral responses.

Unitary System Model

View of executive control as a single system.

Subcomponents of Executive Control

Includes initiating, sustaining responses, and monitoring.

Goal-Directed Behavior

Behavior aimed at achieving specific objectives.

Behavior Initiation

Starting a behavior, often impaired by frontal damage.

Dorsolateral Prefrontal Cortex

Region vital for goal creation and maintenance.

Sequencing

Organizing items or actions in a specific order.

Set-Shifting

Ability to switch between different tasks or rules.

Self-Monitoring

Evaluating one's own actions and performance.

Error-Related Negativity

ERP component indicating self-monitoring of errors.

Inhibitory Control

Ability to suppress well-learned responses.

Right Inferior Frontal Cortex

Region involved in overriding or terminating responses.

Higher-Order Thinking

Complex cognitive processes like abstract reasoning.

Orbitofrontal Cortex

Region for flexible behavior and decision-making.

Working Memory

Short-term memory essential for executive functions.

Causal Control

Control processes vary from caudal to rostral cortex.

Top-Down Set

Influence of lateral prefrontal regions on behavior.

Task Preparation

Readying oneself for upcoming cognitive tasks.

Stimulus Processing

Interpreting and responding to external stimuli.

Response Output

Final action taken after processing information.

Cascade of Control

Sequential control processes from preparation to evaluation.
